The North American PCB book-to-bill ratio increased to 1.05. A ratio of more than one suggests current demand is ahead of supply, which is a positive indicator for sales growth over the next three to six months.

“Although North American PCB sales continued slightly below last year’s levels in February, bookings strengthened,” said Sharon Starr, IPC’s director of market research. “This increased the book-to-bill ratio. The ratio has been in positive territory for the past five months, which is a positive indicator for sales growth in the first half of 2015.”
